STEREOTYPE-PLATE-CASTING IVIAQHINE.

Application filled December 24, 1920.

To all whom it may concern:

Be it known that I, Envns'r J. SMITH, a subject oi. the King of Great Britain, residing in London, England, have invented certain new and useful Improvements in Stereotype-PlateCasting Machines, of which the following is a specification.

The invention relates to a" novel stereotype plate casting machine, and more especially to novel features and structures in such a machine cooperatingtogether to constituteimprovements in construction and in the manner ofoperation.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts. constructions, arrangements, combinations and improvements herein shown and described.

The accompany-ingdrawings, referred to herein and constituting a part hereof, illustrato one embodiment of the invention, and together with the description, serve to explain the principlesof the invention.

The invention in the embodied form is exemplified in a stereotype plate casting machine having the casting members con sistiug of a vertical rotatable core and a concave or drag, the drag rocking from the vertical casting position through a vertically disposed arcuate path down to an inclined position, rendering the changing of matrix sheets both easy and rapid.

The invention provides for the stripping of the matrix from the cast plate before, and preparatory to, the movement of the drag or concave away from the casting position and prior to the rotation of the core toremove the plate from casting position. 7

In the embodied form of such matrix stripping means the matrix holding clamps are mounted on a part of the drag which backwardly and forwardly movable relatively to the remainder of the drag, that is. the matrix sheet carrying part is independ ently movable toward and away from casting position. The mechanism is shown operated by hand actuated means.

The cast plate is moved longitudinally of the'core to remove it prima'rilyfrom the casting position and to bring it into operative relation to the means for cutting off the riser, and later, for delivery from the machine. e

The embodied form of such means comprises a device engaging with the cast plate and lifting it longitudinally of the casting core, that is, a portion of the wall of the casting chamber is shaped so that the plate will cast in engagement therewith,-that portion thereafter moving 'vertically and taking the plate with it. This operation is rendered automatic and is called into action by the movement of the drag away from casting position.

The invention comprises also power operated means for rotating the core to bring a plate from casting position to delivery position, this operating automatically concurrently with the removal of the drag from casting position just after the plate is cast.

In accordance with one feature of the invent-ion, the various functions-of the machine, such as swinging of the drag between its two positions, liftingof the plate along the core after being cast, rotation of the core, and cooperating functions are controlled by a single manually operable lever; and preferably there are a plurality of such levers any one of which can be operated for the purpose stated.

The foregoing features of the invention will be detailed hereinafter, and other features of the invent-ion will be first set forth in connection with the following detailed description of the present preferred embodiment, the foregoing general and the following detailed description. being, it will be understood, exemplary and explanatory of the invention and not unnecessarily restrictive thereof.

In the embodiment of the invention illustrated by way of example in the accompanying drawings, a casting machine is provided with a vertically disposed, rotatable core 1 and cooperating therewith a concave or drag 2 swinging backwardly from the core in a vertically disposed arcuate path.

In the embodied form, the concave or drag 2 is provided with a matrix carrying back 3, which is movable relatively to the remainder of the drag atthe casting position to strip the matrix from the cast plate preparatory to the drag being swung backwardly from casting 1130511131011. The plate is then moved from the caning position to the delivery position while carried by the rotating core, the plate as being removed from the core in a direction longitudinal to the axis of the core.

Referring now to the specific mechanism for rocking the drag or concave 2 to and from casting position, in the embodied form thereof the means for so moving the concave 2to and from casting position (Figs. 1, 2 and 3) and the means for moving the matrix carrying back relatively to the rest of the concave casting member (Figs. 1, 2, 3, 6 and 7) cooperate together, and are also structurally connected together.

Referring first to the means for rocking the concave member 2 in its vertically disposed arcuate path to and from casting position, arms 5 and 6 are fixed to a shaft 7,

which shaft is journaled in the side frames ed at either side upon shaft 10, and are 0011- nected, respectively, to arms 17 and 18.

Arms 17 and 18 have their respective hubs I fixed to a shaft 20, which shaft is journaled in the machine frame. Links 13 and 14 are provided, if desired, with adjustment devices, such as turn-buckles 15 and 16, respectively. I

Fixed on the shaft 20, at either end thereof, are two crank arms 21 and 22, provided, respectively, with handles 23 and 24:, which serve to rock the shaft 20 and thereby,

through the connections described, to rock i the shaft 10 about the shaft 7 The concave 2 is connected to the shaft 10 so that the rocking of theshaft 10, just referred to, will carry the drag or concave 2 to and from casting position. As embodied, the concave 2 has fixed thereto and projecting b-acliwardly therefrom two arms 27 and 23, having their respective hubs 29 and 30,

journaled upon the shaft 10. Spacing collars 31 and 32 are also shown fixed to shaft 10.

Means are also provided for so swinging the concave 2 from the other end of the machine (Figs. 1, 2 and 3), and as embodied, the end of the shaft 20 is provided with a sprocket wheel 35, over which runs an endless sprocket chain 36. Sprocket chain 36 also runs over a sprocket wheel 38, which wheel is journaled in the part 39 of the machine frame. the sprocket wheel 33 is an arm 11, having a handle 42, similar to the handles 23 and 24-, and connected thereto as described. Thus by rocking the arm 41, throughthe connections described, shaft 20 is rocked, and thereby the concave 2 is swung to and from casting position. The operation of the parts in effecting this movement will be understood from Figs. 1, 2 and 3.

Means are provided for stripping the matrix from the cast plate at the casting position (Figs. 1, 2, 3, 6. 7 and 12), so that the matrix will be free from the plate before the plate is carried away by the core. The matrix, of course, is mounted upon and travels with the drag or concave 2. In the embodiedform of said means, the part 3,

which may be conveniently called the mov- Fixed to the shaft 40 of lli able-back, of the drag or concave 2, carries the matrix. The part 3 is movable backwardly or away from casting position relatively to the remainder of the concave 2. For this purpose part 3 is mounted in suitable guides in the concave 2, and is provided upon the exterior of the central back part thereof with lugs 48 and 4-9, which are apertured to receive a wrist pin 50.

Pivotally connected to the wrist pin 50 is an eccentric strap 51, mounted peripherally upon an eccentric 52, which eccentric is sleeved loosely on shaft 10. Fixed to or integral with the eccentric 52 is an arm 53. pivoted by a link 54 to an arm 55. Arm is fixed to or integral with a sleeve 57, loosely mounted on the shaft 20. The linlr is preferably provided with an adjustment, such as a turn-buckle56.

Fixed to or integral with the sleeve 5?, is a hand lever 58, provided with a latch lever 59, pivoted upon the lever 58 at 60, and having :a latchfil adapted to engage, as lever58 is moved, at various points along a toothed sector .62, carried by a plat-e 63 fastened by suitable means, such as bolts to the machine trame.

To effect the automatic stripping of th matrix 1 from the plate when the back recedes, the back 3 is provided with matrix clamping jaws 69 and 70, which are spring:- pressed and hold the matrix y along its straight edges, in the usual manner. The clamping jaws are pivoted respectively at T1 and 72 upon the back member 3 and when the back member isretracted from casting position, these jaws by their spring action are adapted to swing the matrix and strip it away from the cast plate. The details ot construction of the automatically cting' matrix carrying jaws 69 and are not shown herein, but may be generally similar to those shown in application Sci: N0. 108.- 203, of Albert A. Henzi, filed September 4t, .1920.

In the operation. of the foregoing incclmnism, the parts are shown in Figs. 6 and T, in casting position and in retracted position, respectively. and in Fig. 6 the movable back 3 is at casting position as well as the con cave 2. By rocking the hand lever 58 from the position of Fig. 6 to that of Fig". 7, eccentric 52' is rotated and the movable back '3 is retracted or moved backwardly relatively to the concave member 2, and the matrix 3 stripped from the plate as described, preparatory to and immediately preceding the recession or the drag 2 and the rotation of the core 1.

In accordance with certain features of the invention. the plate li er cast ng is moved or delivered in the an al direction along the core 1 to bring it into relation with the tail cutting same and into proper relation with the delivery means prior tothe rotation of the core which carries the plate from -,CELSt'- ing position to the delivery position. In the embodied form of such means (Figs 2, i: and 10), the upper part of the core 1 is irovided with an external portion or shell bl, which fits closely the internal portion of the core l, as will clearly be seen from l'" l and i0. "lhe external portion or shell 81 rotates with the ren'iainder of the core, but is movable longitudinally of the core, that is, in the axial direction thereof, and carries the plate With it in such movement. in the detailed exemplary construct on, the shell 1' and the body 80 ot' the core are contogether by longitudinally disposed fitting into recesses forineclin the j surface of both the shell 81 and 80 ot the core.

:ring further to the details of strucc the core 1. in addition to having a g upon the machine base 83, is jourl on shaft 8%, extending upwardly the machine base within the core. At end shaft 84. (Fig. t) has a cr 8 over which fits a hub or sleeve ined on the head of the part 80 of The shell 81 has a conical upper 8'7. connected to a sleeve 89, so that shell P1 is free to rotate with core 1 r to the sleeve 89, but the sleeve ell 8i. will have longitudinal or enient together relatively to the a purpose. bolts 88 fasten plates .ular ring 90 to the part 87 of t 1e the plate or plates 90 engaging outwardly extending collar '91,

with the sleeve 89, and

are provided For imparting longi tudinal or axial movement to the sleeve 89, and thereby to the shell '81, the shell 81 l cl. to later rotate with the core urging the plate from the casting in to the delivery position. For this csc. the sleeve is journaled in the piece 94-. the machine frame, and in t rotary movement by a spline with the sleeve and with the "l on the 'e.. ternal cylindrical e is a square screw- 1 whir meshes an internal tareao iin a sprocketwheel 97. e sp Let wli 9T rests upon "the e piece and is held in place, that is, 'ng vertically by a healing piece 98 on the top of the hub 86 of the l. and t ncd thereto by suitable such a 5 row bolt 99. 7

Suitable means are provided for rotating the "t wheel 97 to impart the longithread 96, w l

plate. .ln the embodied form of said means,

lower end of shaft 102 and just above the bearing 107, an arm 108 is keyed to the shaft 102, its hub resting upon the bearing 107. Pivotally connected to the outer end of the arm 108 is a rod 109.

Rod 109 at its opposite end is pivotally connected to a lever 110, which lever is pivoted at 111 upon the machine frame. At its opposite end, lever 100 is provided with a cam roller 112, which works in a box cam 113. Cam 113 .is formed in a plate 114, which plate is fixed on the shaft 20 to oscillate or swing therewith.

When the shaft 20 is rocked by means of any of the arms 21, 22 or 41., the cam plate 114 is rocked between the positions shown in Figs. 1 and 2, thereby rocking lever 110. This rocks arm 108, which imparts rotary movement to shaft 102, and sprocket wheels 101 and 97, the rotation of sprocket wheel 97 imparting longitudinal movement to thesleeve 89, and therewith to the plate carrying shell 81 and to the plate :1; carried thereby.

Thus when the drag or concave 2 is swung down from the casting position of Fig. 1 to the delivery position of Fig. 2, the shell 81 is lifted and therewith the plate m, the plate being thereafter rotated to delivery position with the core 1. As the drag 2 is swung backwardly again from the position of Fig. 2 to that of Fig. 1 preparatory to casting, through the mechanism justdescribed, sprocket wheel 97 is rotated in the opposite direction, and the shell 81 descends again to the position for casting ready for the casting of the next plate.

For the purpose of carrying the cast plate with the shell 81, the latter is provided with recesses adapted to form slight projections upon the tail or riser of the plate, and such recesses 117 are provided designed to insure rotary movement of the plate with the core, the axial or longitudinal movement of the plate with the core being ef fected by the conical conformation of the upper part of the shell 81. 1

Means are provided for holding the core in casting position, and for releasing it for rotary movement in proper sequence with the remainder of the mechanism. As embodied, said means (Figs. 3, 4, 5 and 11) are controlled and operated from the means for moving the concave or drag 2 to and from the casting position. In such. embodied form, recesses 124 are formed in the base of the core 1 (Fig. 3), and cooperating therewith is a spring-operated detent 125 mounted in a bearing block 126 for longitudinal movement therein, the detent being acted on by a spring 127 within the block. The detent 125 at its outer end 128 is pivotally connected to a lever arm 129, which is fixed to a shaft 130, journaled in bearings 122 and 123 on the machine frame. Fixed also to shaft 130 is an arm 131. Pivoted at 132 to arm 131 is a longitudinally slidable rod 133, slidable in bearings 134 and 135, mounted on the machine frame.

The rod 133 is acted on by a spring 137, fixed at one end 138 to the machine frame and at the other end 139 to the rod 133, thereby impelling the detent 125 resiliently into engaging position with the recess 124 in the core 1. For the purpose of retracting the detent 125 to release the core 1,

rod 133 is provided with a hook 140 at the end thereof. On the hub 141 of arm 21 is mounted a spring-actuated detent tooth 142, slidably .mounted in a bearing block 143, which is fixed to the hub 141 by screw bolts 144. The detent 142 is acted on by spring 145 in compression between a shoulder on the detent tooth 142 and the bottom of the recessed interior of the block 143.

When the arm 21 is swung upwardly in Figs. 2 and 11, to move the concave or drag 2 from casting position, the tooth 142 will engage the hook 140 and draw rod 133 to the left in Fig. 11, that is, to the right in 'Fig. 3, thereby withdrawing the detent 125 from the recess 124 and leaving the core 1 free to rotate. As the arm 21 continues to rotate from the position shown in Figs. 1 and 11 to that shown in Fig. 2, the detent tooth 142 will arc out of the hook 140, and spring 137 will pull back rod 133. This will cause detent 125 to press against cylinder 1 and to be ready to snap into the recess 124 in the core 1 as it comes around and will again arrest the core 1 in proper casting position.

The embodied form of means for intermittently rotating the core 1, to bring the successively cast plates from casting position to delivery position, comprises a worm wheel 155 formed on the base of the core 1, with which meshes a worm 156 (Figs. 1, 3 and 4). Worm 156 is fixed on a sleeve 157. which sleeve is loose on a shaft 158, the shaft being journaled in bearings 159 and 160 mounted upon the machine frame. Fixed to the sleeve 157 is a clutch member 162, adapted to cooperate with a clutch member 163, which is fixed on the shaft 158 to rotate therewith by suitable means, such as a pin 164 passing through the hub of the clutch member 163.

The clutch members 162 and 163 are yieldingly impelled into engagement by suitable means, and as embodied a spring 165 is coiled about shaft 158 and is in compression between the sleeve 157 and a collar 166, fixed on shaft 158. To drive shaft 158, there is fined thereon a worm wheel 17 0," with which meshes a worm 171, which is keyed to a shaft 172. Shaft 172 is journaled in bearings 173and 17%, mounted on the machine frame, and is rotated by any suitable means. As herein shown, a belt pulley 175 is fixed on shaft 172, over which runs a belt 176, running over pulley 177, fixed on the shaft of a motor 178.

The shaft 172 is preferably continuously driven, and the shaft 158 is likewise preferably continuously driven therefrom. The detent 125 may be regarded as withdrawn from the recess 124- in the core 1, and the core 1 is free to rotate. The spring 165 im-' pels the clutch aw 162 into engagement with the clutch jaw 163, thereby rotating the worm 156 from shaft 158, thereby through the worm wheel 155 rotating the core 1 When the core 1 hasmade a semi-rotation detent 125 engages the" recess 12%, and stops the rotation of the core 1. rotation of the worm 1'55, and clutch member 163 continuing to rotate with shaft 158, clutch meniiber 162 is forced out of engagement with clutch member 163, against the action of spring 165.

Means are provided for cuttingofi' the tail or riser from the cast plate as, and in the embodied form (Figs. 4 and 12) of such means, a beveled gear 185 is fixed oil-shaft 172. hileshing with beveled gear 1851s a beveled gear 186, which is mounted: loosely on shaft- 102.

over a sprocket wheel 189, fined on a shaft 190.

Shaft 190 is ournaled in hearings 191 and 197 into and out of cutting position withrespect to the cast plate. In accordance with one feature of the invention such movement of the saw is automatic and is e'li'ected by the mechanism which swings the drag 2 back from casting position and starts the core 1 in its rotary motion. As: enibodied (Figs. 1, 1 and 12), a rod or con necting link 200 is pivoted at 201 to the bracket arm 193 of the support for saw 197. it its other end 202 the link or rod 200 is pivoted to a lever 203. which lever is pivotally mounted at204s upon theniachine frame;

This stops the Fixed to the hub ofbeveled gear 186 is a sprocket wheel 187, over which runs a sprocket chain 188, which also runs- At its opposite end lever 203 is provided with acam roller 205 working in a box cam 206 f0-rmed in a camplate 207, which plate is fixed on shaft 20.

Thus as the shaft 20 is rocked to swing the drag 2bac'k from casting position, and just prior to-t-he'beginning of the rotary motion ofthe core 1, the saw 197 is swung into position to engage with the plate at, and as; the core 1 rotates to saw off" the riser. When shaft 20 is rotated in the opposite direction to bring the drag 2 back to casting position, the saw 197 is swung backwardly to the dis engaging position; as shown in Fig. 12. The saw may-be proportioned to project slightly intothe space'left betweencore and sleeve 81 and thus will entirely and cleanly sever the plate from the tail.

The delivery station is shown in Figs. 1, 2, and 12, and comprises a platform 210, with the inner edge abutting on the" core 1 of arcuate form to conform to the shape of the core. The platform 210 is vertically adjustable, and for this purpose'is provided with recessed sides to take guides 211 and 212, formed respectively on posts 218 and 214C. The platform 10 is provided with depending portions, through which pass respectively bolts 215 and 216,- which bolts pass throu'gl'i slots 217 in the posts 213,and 2141-, thereby providing vertical adjustment for the plate receiving platform 210.

The manner of operation of the various inec'l'i'anisms hasbeen described inconnection wit-h the detailed description of the str-ucture ofthe various parts; but a briefsummary will be given as-follows':

The drag 2 may be regarded as in the-casting position, as shown in Fig. 1, and a plate may be regarded" as just having been cast. Aftert'he plateisso' cast, lever 58' isswung from the position of Fig. 6 to that of Fig; 7, and the matrix carrying back- 3- is thereby retracted; and the spring clamps 69 and 70 are thereby caused to strip the matrixfrom the cast plate. One of tl'ielevers; 21', 22' or 11 is swung fromthe position of Fig; 1 to that of Fig 2, thereby retracting the drag 2 from casting position as shown in Fig; 1 to the positionof Fig. 2.

When thedr-ag is swung back in the manner described, cam' plalte 1141 rocks with sh aft 20, and lever 110 is actuated, thereby imparting rotation to'sha'tt 1'02, and the'shell 81 is raised'vei' tically and therewith the plate 00 which has just been cast.

The swinging of arm 21' has retracted detent 125 from the recess 12%, releasing core 1, which is then rotated through worm wheel 155 and worm 156" for ahalt'rotation bringing theca'st plate to the delivery position.

Also when shaft 20 isrocked, cam plate- 207 rocks therewith, and swings the saw sition of Figs. 3 and 4, thereby cutting off the tail or riser from the plate. As the semirevolution of core 1 is completed, detent 125 enters a recess 1% in the core 1, and brings the core to rest with the cast plate at the delivery position, theclutch 162, 163 being thrown out. The machine is now in position for casting the next plate, whereupon the operations as herein described are repeated. If the lever 58 be left in the position shown in Fig. 6 and the casting box he opened, the matrix carrying back 3 will simultaneously recede automatically and the matrix will be thereby stripped automatically. This manner of operation may be optionally employed instead of preliminarily receding the back as already described.

The bottom of the casting chamber is formed in the present instance by the horizontal projection from the core just'above the worm wheel 155 and may be regarded as the upper fiat face of the worm wheel.

The straight vertical sides of the casting chamber are formed by the edges of the mat-' rix clamps 69 and 70 opposite tie plate and by like parts formed on the core or the sleeve 81 opposite the tail of the plate.

In Fig. 13 a form of rib 80 on the cast ing device is shown designed to especially facilitate the removal of the plate in the axial direction of the core, although the ordinary or other suitable form of rib may be employed if desired.

Suitable cooling means for the core of any V standard or suitable type or kind may be provided, but are not shown herein, and the same may be provided for the drag also if desired.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
